IMPROVEMENT IN LEAD-PENCILS.

Specicaton forming part of Letters Patent No. Rd, dated December 3l,1872.

To all whom it may concern:

Be it known that I, SAMUEL D. Hovnv, of Brooklyn, in the county of Kingsand State of New York, have invented certain Improvements in Pencils, ofwhich the following is a specification, reference being had to theaccompanyin g drawing.

My invention relates to the attachment of rubber-erasers to pencils; andthe invention consists in the use of a paper tube for attaching andprotecting the rubber, as hereinafter explained.

The Figures l, 2, 3, and 4 represent the various methods of applying myinvention.

I first construct a short paper tube, as represented by B of the severalfigures, and secure in one end of it a piece of rubber, C, as shown inFigs. l and 2, the rubber protruding therefrom, as represented, so as tobe conveniently used for erasing pencil-marks onpaper. The rubber may besecured to the paper tube by means of a small nail or rivet, e, as shownin Figs. l and 2, or it may be cemented or fastened in any suitablemanner.

When thus arranged, as represented in Fig. 2, the papertube B is slippedon the end of the pencil A, as represented in section in Fig. l, inwhich case the pencil is provided with an eraser at all times ready foruse.

In Figs. 3 and 4 I have shown a modified y plan of applying the papertube. In this case the rubber C is secured permanently to the end of thepencil, and the paper tubeB is then slipped loosely over both rubber andpencil, and held on by a pin, e, which passes through a slit, l,previously made in the tube B, and is driven into the pencil A, asrepresented in Figs. 3 and 4. By this means the tube B can be shoved upso as to cover the rubber, as indicated by the dotted lines in Fig. 4,and thus protect the eraser from be coming soiled when carried in thepocket. If

desired the rubber can be thus arranged to.

slide in the tube, and be then used separate from the pencil, it thusforming a convenient pocket-eraser, the tube serving both as a handleand as acase for protecting the rubber from becoming soiled or greased,which would impair its utility and soil the drawing or paper on which itis to be used.

These paper tubes can be made much cheaper than the metal tubes used inmy patent of -August 17, 1869, being sufficiently durable to Witnesses:
